Retinal Usage

Retinal, also known as vitamin A aldehyde, is extremely sensitive to light. When the concentration is too high (0.5% or more), it is easy to irritate the skin, and should be avoided as much as possible with whitening ingredients (prone to irritation).

Retinal can effectively prevent photoaging, hinder abnormal pigmentation of the skin, and prevent rough skin;

Retinal can be used to treat inflammatory skin infections. Long-term use of retinal in 0.1% to 0.05% concentration is not only effective in the treatment of dermatological conditions, but can also be safely used unlike other vitamin A solutions, it cannot be used as a long-term treatment. Skin condition.

Retinal may reverse wrinkles, inelastic skin and mottled appearance.
